Abstract:
Eight compounds have been isolated for the first time from Vernonia cinerascens namely, 2-hydroxy-3-methoxy-5-(2-propenyl)-phenol (1), vanillic acid (2), isoferulic acid (3), caffeic acid (4), methyl gallate (5), uridine (6), 3'-methylquercetin (7) and quercetin (8), respectively. Their structures have been elucidated based on EI-MS, HREI-MS, FAB-MS, HRFABMS, 1 H-, 13C-NMR spectroscopic data and in comparison with the reported data. All these compounds exhibited promising antioxidant and significant urease inhibitory activities.
